Get customer data by email in Magento 2

In Magento 2, retrieving customer data based on their email address is a common requirement for various customization and personalization tasks. Whether you need to personalize communication, provide targeted offers, or perform data analysis, accessing customer data by email is crucial. In this article, we will explore how to efficiently retrieve customer data using the CustomerRepositoryInterface enabling you to enhance the customer experience and drive business growth.

Understanding the CustomerRepositoryInterface

The CustomerRepositoryInterface is a fundamental part of the Magento 2 Customer API, providing a standardized way to interact with customer data. This interface offers methods to retrieve, create, update, and delete customer records in the Magento 2 database. By utilizing the CustomerRepositoryInterface, we can efficiently retrieve customer data based on their email address.

To retrieve customer data based on their email address in Magento 2, you can use the following code snippet.

<?php


namespace Learningmagento\Customer\Model;

use Magento\Customer\Api\CustomerRepositoryInterface;
use Magento\Framework\Exception\NoSuchEntityException;

class CustomerDataFetcher
{
    protected $customerRepository;

    public function __construct(CustomerRepositoryInterface $customerRepository)
    {
        $this->customerRepository = $customerRepository;
    }

    public function getCustomerDataByEmail($email)
    {
        try {
            $customer = $this->customerRepository->get($email);
            $customerId = $customer->getId();
            $customerData = [
                'id' => $customerId,
                'firstname' => $customer->getFirstname(),
                'lastname' => $customer->getLastname(),
                'email' => $customer->getEmail(),
                // Add any additional customer data you need
            ];
            return $customerData;
        } catch (NoSuchEntityException $e) {
            // Handle exception if customer with the provided email does not exist
            // You can log the error or return a default value as per your requirement
        }
    }
}

To retrieve customer data, simply call the getCustomerDataByEmail function and provide the email as a parameter. This function will return an array containing the requested customer data. It can be called from any class or phtml template within your codebase.
